International Classification:

G06F 17/30

US Classification:

707739, 707777, 707796, 707803

Abstract:

One or more classification algorithms are applied to at least one natural language document in order to extract both attributes and values of a given product. Supervised classification algorithms, semi-supervised classification algorithms, unsupervised classification algorithms or combinations of such classification algorithms may be employed for this purpose. The at least one natural language document may be obtained via a public communication network. Two or more attributes (or two or more values) thus identified may be merged to form one or more attribute phrases or value phrases. Once attributes and values have been extracted in this manner, association or linking operations may be performed to establish attribute-value pairs that are descriptive of the product. In a presently preferred embodiment, an (unsupervised) algorithm is used to generate seed attributes and values which can then support a supervised or semi-supervised classification algorithm.

Abstract:

A method and system for identifying nodes with similar content. In one aspect, the method comprises determining a structure of a network of nodes, said structure defined by incoming links and outgoing links between nodes within said network, grouping said nodes within said network into a first set of modules, calculating a first modularity value between each of the modules within the first set, said modularity value indicating a degree of similar content within each module, calculating a topical relevance value for each of the modules, selecting those modules whose topical relevance value exceeds a threshold value and calculating an authority score for the selected modules.

G06F 11/00
G06F 16/11

Abstract:

A system according to certain aspects improves the process of creating secondary copies of data (e.g., creating backup copies). The system can compute the score of the data (e.g., a computer file storing information) to be backed up, and determine whether the score satisfies one or more threshold criteria before backing up the data. In one example, a change in score indicates a change in the content of the data. The threshold criteria may be that the score be different from the score of the most recently backed up copy of the data.

Abstract:

Aspects of this disclosure relate to protecting email data. For example, email protection rules can instruct an email server to route an email to an email protection module. The one or more email rules can identify a group of one or more email addresses. The email protection module can receive an email from the email server that has an email address of the group as an intended receipt. The email protection module can route the email to secondary storage and store the email in secondary storage to create a secondary copy of the email. The secondary copy can be stored inline to persistent memory of secondary storage, according to certain embodiments. Access to the backup copy of the email stored to the persistent memory can be controlled, for example, based on whether a user had permission to access to the email when the email was sent.
